Free plug-ins for Photoshop

Plug-ins are a great way to extend the functionality of Photoshop, adding fun filters and fresh features to the application. Although most plug-ins are modestly priced, there are a number of cool plug-ins available completely free. Here's a round-up of some of the most compelling freeware plug-ins currently available for Photoshop CS3, CS4, and CS5, and Photoshop Elements 8.

You can install plug-ins by dragging the plug-in file into the application's plug-in folder, found at Macintosh HD -> Applications -> Adobe Photoshop -> Plug-ins. Many plug-ins now include their own installer, however, and some newer plug-ins must be installed via the Adobe Extension Manager. Once installed, you can usually find the plug-in under the Filter menu in Photoshop, though some must be accessed through Window -> Extensions.

Note that this roundup consists of just six plug-ins. As I researched this article, it quickly became apparent that while there are a wealth of free plug-ins available for Photoshop on Windows, there aren't many for Photoshop on OS X. Developers say that Adobe's tools make it cumbersome to port Windows-based plug-ins to OS X, and many of these freeware developers see little value in the effort. Moreover, Photoshop's plug-in architecture is constantly evolving, with each new version of the application introducing incompatibilities with older plug-ins. Of the six plug-ins highlighted below, four are effectively marketing tools for paid products from those developers.

Photoshop Edge FX 2.2

Sebastien Piconnier's Photoshop Edge FX 2.2 is a fun plug-in for Photoshop CS4 and CS5 that lets you enhance your photos with an arty graphic border. You start by choosing from more than 60 preset borders and then resize and reposition the border; after that, you can go ahead and apply layer styles such as Glow and Drop Shadow. The borders are applied as masks, which preserves your original photo.

PhotoTools 2.5.4 Free

onOne Software's PhotoTools 2.5.4 Free is a fine collection of photographic filters, including cross-process, cyanotype, sepia toner, and vintage. The plug-in app commands the full screen, placing before and after previews side-by-side so that you can preview the filters as they are applied. Most filters have no options (aside from fade), but they can be combined together to create interesting effects.

Dreamy Photo

Auto FX Software's Dreamy Photo lets you infuse your images with a soft, dreamlike quality. Presets are included for a soft glow, a blurry zoom and a trippy rotational blur. The plug-in is hampered by an awkward interface, but the resulting images are quite compelling. (Note: This plug-in is not yet compatible with CS5.)

Mosaic

Mosaic is another interesting plug-in from Auto FX Software that lets you transform your photos into mosaics with either square, hexagonal, or octagonal tiles. Controls let you set the size of the cell, randomize its shape, and apply depth. It shares Dreamy Photo's clunky interface, however. (Note: This plug-in is not yet compatible with CS5.)

PhotoFrame 4.5.2 Free

onOne Software's PhotoFrame 4.5.2 Free is a plug-in that lets you apply graphic frames to your photos, such as film reel, Polaroid, and water color. Borders and textures can be combined to create unique effects, and the resulting border is applied as a layer, preserving your original photo.

Pixel Bender

Adobe's Pixel Bender is an interesting (and for now, experimental) add-on to Photoshop CS4 and CS5 that uses your computer's graphics processor to literally bend pixels. The included filters are a bit hit-and-miss, though you'll certainly be impressed by OilPaint. You can download additional Pixel Bender filters from Adobe Exchange.

(Image Caption: Adobe PixelBender is a little rough around the edges, but filters like OilPaint make it worth the effort.)
